The phrase "a depth gradient of" is correct and usable in written English.
It can be used in contexts related to science, geography, or any field discussing variations in depth, such as in water bodies or geological formations.
Example: "The study focused on a depth gradient of sediment layers in the lake, revealing important historical data."
Alternatives: "a depth variation of" or "a depth change of".
Nonetheless, the fact that species in both genera remain recognizable and have distinct ecological distributions does point towards the importance of divergent/disruptive selection across a depth gradient in the diversification of these genera.
The coils are adapted to the Profile NMR-MOUSE® magnet with a homogeneous slice of about 200 μm in height and a uniform depth gradient of about 20 T/m.
The third axis (14% of variance) shows principally a depth gradient and the fourth axis (12% of variance) exhibits a gradient between sand dwelling sea anemone species living either among or away from coral reefs.
The two genetic lineages of E. flexuosa are found at the opposite ends of a depth gradient.
Therefore, an appropriate combination of these cores could provide a suitable set of depth transect to reconstruct the depth gradient of biogenic fluxes and deep water ventilation in the past.
The results indicate that the residual stresses in the as-deposited films and the amount of stress relaxation depend decisively on the specific depth gradient of point defects originating from film evolution during growth.
Figure 1 Trend of As imbibition along the depth gradient of soil from the surface to 160 ft. As levels were observed to decrease up to a depth of 45 ft (approximately), beyond which the level remained stable.
This means that triangle edges that connect two triangles [e.g., (3, 5) in Fig. 7] result in two equations with possibly different depth differences, one resulting from the depth gradient of triangle (2, 3, 5), and the other from triangle (3, 5, 6).
Resolving depth gradients of microstructure and residual stresses within individual sublayers of multilayered thin films and understanding their origin as well as their influence on functional properties are challenging tasks.
The development of depth gradients of texture, morphology and stresses in thin nanocrystalline films was experimentally demonstrated for a nanocrystalline CrN film by means of position-resolved synchrotron X-ray nanodiffraction and explained by atomistic processes at the growing film surface and the effect of interfaces, both controlled by the deposition conditions.
We measured salt stocks from the surface down to the water-table through soil coring and their horizontal distribution through electrical-resistivity imaging in eleven fields occupied by annual crops, eucalyptus plantations and grasslands, encompassing water-table depth gradients of 1 6 m below the surface.
